We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths
with the Herschel Space Observatory have provided us with unprecedented images of the …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

Binary formation is an important aspect of star formation. One possible route for close-in
binary formation is disk fragmentation,–. Recent observations show that small-scale …

We present results from the first population synthesis study of protostellar discs. We analyse
the evolution and properties of a large sample of protostellar discs formed in a radiation …

Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

We address the problem of the origin of massive stars, namely the origin, path, and
timescale of the mass flows that create them. Based on extensive numerical simulations, we …

Context. The Galactic center is the closest region where we can study star formation under
extreme physical conditions like those in high-redshift galaxies. Aims. We measure the …

Context. The infall of gas from outside natal cores has proven to feed protostars after the
main accretion phase (Class 0). This changes our view of star formation to a picture that …

Context. Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30-m
Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O) …
